Abstract (en)
[origin: WO2012076320A1] The present invention relates to a transmission apparatus and a corresponding transmission method for transmitting data within a multi-carrier transmission system comprising two or more transmission apparatuses that are configured to transmit the same data. To avoid destructive interferences a transmission apparatus (10) is proposed comprising a signal input (30) configured to receive multi-carrier signals (S(k)) carrying data to be transmitted, a distortion unit (32) configured to distort said multi-carrier signals (S(k)) by use of a distortion function (P(k)) including a phase parameter for differently modulating the phase of said multi-carrier signals (S(k)), wherein said distortion function (P(k)) is different from distortion functions used by other transmission apparatuses, whose coverage areas overlap with the coverage area of the present transmission apparatus, by using a phase parameter that is different from the phase parameter used by said other transmission apparatuses, and a transmission unit (34) configured to transmit said distorted multi-carrier signals as transmission signal (Tx(k)).
